this should show verbose (extra output). BTW, you said that '/proc/swaps' was completely empty - could you try again and check that you did a:
cat /proc/swaps
as opening this 'file' in a text-editor (such as 'gedit') will not work. It is a special file that doesn't actually exist; so it can't be 'opened', but the contents can be 'cat'ed.

sudo update-initramfs -u $(uname -r)
to recreate it for your currently running kernel.

sudo swapon -av
